Thread Subject:
Three Phase Rectifier

Subject: Three Phase Rectifier

Hi Everybody,

I need some help in a project I'm working on. I am working on a control
system for a Three Phase AC (line frequency) to DC converte, using the good
old fashioned method of SCRs (thyristors). Is there a simulink model for a
Three Phase SCR (Thyristor) Based Rectifier. Please help.
Thanks in advance.
Srikanth

Hello Shrikantha,

I only know the "6-pulse thyristor bridge" of the power system blockset.
But it seems that it's only 6thyristors put together. No control.

Hi,

If you have the Power System Blockset on hand, it has some
pretty good demos that you could use.
If the demos don't have what your looking for, send me a mail
and I'll send you a 12 pulses thyristor rectifier (with YYD transformer,
and filter banks) which I used frequently as a test circuit and which
works fine. It's open loop, so you can plug in any controler you want.
But I'm quite sure that you'll find what you need in the PSB's demos.

You may want to consider developing your electrical system model using
a different tool an then importing it somehow into Simulink. For
example, Dymola (http://www.dynasim.se) allows you to generate
S-functions for Simulink directly from electrical schematics.
Furthermore, since Dymola uses Modelica and several (free) electrical
component libraries exist in Modelica (http://www.modelica.org) you
might find exactly what you need.
